Packaging system

ABSTRACT

There is described a packaging system ( 11 ) which comprises a first chamber ( 12 ) adapted to house a first material ( 15 ) and a second chamber ( 13 ) adapted to house a second material ( 18 ), the first and second chambers being separated by a frangible member ( 14 ). There is also described a sanitary article packaging system which comprises such a system.

[0001] The present invention relates to a novel packaging system.

[0002] In particular the invention relates to a packaging system whichis adapted to separate house components which may subsequently be mixed.

[0003] There are numerous situations whereby packaging systems areutilised to separate components which are mixed just prior to use, forexample acrylic adhesives are usually supplied as a tube of acrylicmonomer and a tube of polymerisation initiator. The user mixes themonomer and initiator prior to use. However, one disadvantage of suchsystems is that one of the two tubes may be lost rendering the systemuseless. Furthermore, mixing of the monomer and initiator is a two stepprocess and also requires the use of a mixing surface.

[0004] Also, many food products are marketed as multi component systems,for example, yoghurts are often presented in a carton with a separatefruit chamber so that the user can mix the fruit into the yoghurttogether in desired quantities. Similarly, many products are availablein the form of a“dip”, for example, bread sticks with a cheese dip ornachos with a spicy dip, and many others. Such products, like yoghurts,comprise a plastics member which comprises two chambers with aremovable, usually foil, lid.

[0005] Again this cannot be a one handed process and also is unsuitablefor use as a fast snack food since a spoon or other utensil is required.

[0006] Thus we have developed a novel packaging system which overcomesor mitigates this problem.

[0007] In particular embodiment the invention relates to such systemscomprising means for applying medicaments and/or lubricants. Thus, theinvention is especially useful in applying medicaments or lubricants toabsorbent articles, e.g. sanitary articles or cotton buds, etc.

[0008] In the field of sanitary products, it is known that theapplication of a dry, absorbent sanitary product, for example acatamenial tampon, to or into moist body tissue, often causesdiscomfort. This is largely because the often filamentous externalsurfaces of the sanitary product absorb moisture and adhere to andirritate the tissue.

[0009] It is known to attempt to solve this problem by lubricating theproduct's external surfaces. In one form, such lubrication consists oflow-friction cover nets, meshes and webs and other perforate layersconstructed to be capable of deforming resiliently, and permitting thepassage of bodily fluids.

[0010] Alternative approaches have included fluid surface lubricants.However, problems associated with such lubricants include the fact that,over time, the sanitary article may gradually absorb the surfacelubricant which may, inter alia, lead to a loss in absorbency in thearticle.

[0011] U.S. Pat. No. 4,428,747, attempts to overcome this problem with ablister package for holding, e.g. a sanitary tampon, which includes atrough which is adapted to act as a lubricant reservoir. In oneembodiment the reservoir is provided with a removable cover. However,such a device suffers from the disadvantage that, inter alia, the troughrenders the packaging bulky, and the complicated construction isdifficult and expensive to manufacture. Moreover, the design requiresthat the tampon be removed and dipped into the lubricant. Furthermore,the system cannot easily be incorporated in an integral tamponapplicator.

[0012] The novel form of packaging which we have developed alsoovercomes or mitigates some of the disadvantages of prior art methods ofdelivering, e.g. lubricated tampons.

[0013] Thus, according to the present invention we provide a packagingsystem which comprises a first chamber for housing a first material anda second chamber adapted to house a second material, the first andsecond chambers being separated by a frangible member.

[0014] In particular, the use of a frangible membrane in the packagingsystem of the invention allows the first and second materials to bebrought into contact with each other without opening the packagingsystem. Thus, the frangible member should be such that, once ruptured,one or more apertures should be created between the first and secondchambers, permitting material in the first chamber to be mixed orcontacted with material in the second and vice versa.

[0015] A wide variety of materials may be housed in the first and secondchambers. Examples of such materials include, but are not limited to,yoghurts and fruit sauces; polymerisable adhesives and polymerinitiators; shampoos and colouring or conditioners, bread sticks anddip, sausages and dips, cake or biscuit bar and cream, chocolate orfudge sauce, e.g. ice-cream, desserts with fruit, chocolate or fudgesauce.

[0016] However, in an especially preferred aspect of the invention thepackaging system houses a medical or a sanitary article. Thus, accordingto this aspect of the present invention we provide an absorbent articlepackaging system which comprises a first chamber for housing anabsorbent article and a second chamber adapted to act as a substratereservoir, the first and second chambers being separated by a frangiblemember.

[0017] As the system of the invention can be used for absorbentarticles, e.g. cotton buds, sanitary articles or medical articles,reference herein to sanitary articles should be construed as includingmedical articles and/or cotton buds. Sanitary products include femininehygiene products, for example sanitary tampons. Medical products includeany dressings, including tampons, where it is desirable to, for example,lubricate or medicate a wound contact surface, cavity wound dressings.

[0018] The system of the invention is especially suited for housing asanitary tampon, for example a tampon of conventional design withcoverstock and removal cord.

[0019] Suitable materials for the housing include at least one flexiblesynthetic polymer, such as a thermoplastic, for example a polyester orpolyamide (e.g. nylon™), polypropylene or polyethylene or otherconventionally known polymer materials. Elastomeric materials may alsobe used (for example elastomeric polyurethanes) and may be incorporatedtogether with non-elastomeric material of the film, membrane or sheet.

[0020] Preferred materials for the housing are polyethylene laminates,examples of such laminates include laminates of polyester/polyethylene,polypropylene/polyethylene, nylon/polyethylene andpoly(ethyleneterephthalate)/polyethylene. The most preferred laminate ispoly(ethyleneterephthalate)/polyethylene (PET/PE) and especially one inwhich the PE is a peelable PE.

[0021] The first and second chambers, may be formed of the same, similaror different materials, the last-mentioned including at least one rigidsynthetic polymer, such as a thermoplastic, for example a polyester orpolyamide (e.g. nylon™), polypropylene or polyethylene, or other polymermaterials. However, it is preferred that the first and second chamberscomprise the same material so that, for example, they may bemanufactured from a continuous strip of material.

[0022] Other materials that may be used include cellulosic materials,for example sheet materials, such as cardboard. When an absorbentsurface like card is used then the substrate chamber is preferentiallycoated with a moisture and/or substrate resistant coating such assilicon, wax or cellophane or, alternatively, acrylic papers may beused.

[0023] The thickness of the walls of the system may vary and maytherefore be from 40 to 100 μm in thickness for each laminate. Thethickness of each of the walls may be the same or different. Preferably,when the laminate comprises a PET/PE laminate, the PE layer is ofgreater thickness than the PET layer. The PET layer may be from 10 to 20μm in thickness, preferably 10 to 15 μm. A thickness of 12 μm is mostpreferred. The PE layer may be from 30 to 80 μm in thickness, preferablyfrom 35 to 70 μm and most preferably from 40 to 65 μm and especially 40or 50 μm. A particularly preferred embodiment comprises a first wallcomprising a laminate of 12 μm PET and 50 μm peelable PE; and secondwall of 50 μm PET and 65 μm peelable PE.

[0024] In one embodiment one or both of the walls may be metallised.

[0025] The substrate reservoir in the sanitary article packaging systemwill generally be adapted for providing the substrate only or mainly tothe external surface of the sanitary article where it will provide theleast hindrance to absorption of bodily fluids. An example would includethe nose of a catamenial tampon.

[0026] The frangible member may comprise a frangible membrane. However,alternatively the frangible member may be created by the bondingtogether of the walls of the chamber. Such bonding may comprise pressurecrimping, heat crimping or the use of an adhesive, or any combination ofthe aforesaid means.

[0027] In the most preferred embodiment of the invention of thefrangible member is created by a combination of heat and pressurecrimping. The pressure and temperature applied will vary, dependingupon, inter-alia, the nature of the material, the nature of thesubstrate, the depth of seal desired, etc.

[0028] Thus, according to a yet further feature of the invention weprovide a process for the manufacture of a packaging system ashereinbefore described which comprises heat and/or pressure crimping aportion of a strip material to create a first chamber for housing afirst material and a second chamber adapted to house a second material,the process of heat and/or pressure crimping creating a frangible memberwhich separates the first and second chambers.

[0029] In accordance with a preferred aspect of the invention we providea process for the manufacture of a sanitary article packaging system ashereinbefore described which comprises the steps of;

[0030] (i) heat and/or pressure crimping two strips of a laminatematerial along a first longitudinal edge;

[0031] (ii) heat and/or pressure crimping in a direction perpendicularto the first longitudinal edge seal to create at least three seals,being first and second end seals and a frangible member, said threeseals creating first and second chambers;

[0032] (iii) placing a sanitary article and a material in theirrespective first and second chambers;

[0033] (iv) heat and/or pressure crimping along a second longitudinaledge; and

[0034] (v) cutting to produce a sanitary article.

[0035] It may be optional to include step (v) as part of one of theearlier steps, e.g. step (ii), thus the heat and/or pressure crimping tocreate the first and second end seals may incorporate cutting step whichmay be separate, simultaneous or sequential to the sealing step.

[0036] Under laboratory conditions a preferred temperature ofheat/pressure crimping is from 125 to 160° C., preferably 130 to 150°C., most preferably about 140° C.

[0037] A preferred pressure for heat/pressure sealing is from 10 to 20psi, preferably 14 psi.

[0038] The duration of the crimping may vary and may be from 0.5 to 2.0seconds, preferably 0.5 to 1.5, most preferably 1 second (underlaboratory conditions).

[0039] The depth of the seal for the frangible membrane may vary and maybe from 1 to 10 mm, preferably from 2 to 8 mm, more preferably from 2 to6 mm and most preferably 3 mm.

[0040] If the periphery of the chambers are crimp sealed then the depthof the seal may be from 2 to 10 mm, more preferably 3 to 8 mm, morepreferably 4 to 6 mm and especially 5 mm.

[0041] The use of the system may vary depending upon the nature of thematerials housed therein. Thus, for example, a bread stick housed in thefirst chamber is pushed into the second chamber, eg containing a cheesesauce, breaking the frangible member. The sauce substantially coats thebread stick and either one or both of the chambers may then be opened tofacilitate removal of the food item.

[0042] Alternatively, for mixing, for example, yoghurt and fruit sauce,one or both of the chambers may be squeezed, the pressure may rupturethe frangible member allowing the two materials to mix or to allow thecoating of, e.g. an applicator tampon (that cannot itself be forcedthrough the membrane).

[0043] Alternatively, when the system houses a sanitary article thesubstrate may comprise a variety of materials, such as medicaments,cosmetics, drugs, hormones, probiotics or lubricants. Examples ofmedicaments include antimicrobial agents, such as triclosan orchlorhexidine; or antifungal agents, such as clotrimazole. Medicamentsalso includes homeopathic medicines and/or aromatherapy materials.Examples of lubricants include extracts of sea algae, such as alginates,agar, cararageen; exsudates of plants, such as tragacanth, gum arabic;extracts of plants, such as pectins, starch fractions and derivates,such as dextrins, amylopectins, hydroxyethyl starch; derivates ofcellulose, such as methyl, ethyl, and hydroxypropyl cellulose; fattysubstances such as mono, di, triglycerides of higher saturated fattyacids, polyalkylene glycols and other ethoxylated products, such aspolyethylene glycol 200-4000, PEG-G-capryl/caprine glyceride;hydrocarbons, such as paraffin oils, vaseline; polymers, such aspolyvinyl alcohols, polyvinyl pyrrolidones, polyacrylates; alcohols,such as ethylene glycol, glycerol; emulsifiers, such as alecithin,cholesterin, or derivates of the sorbitan fatty acid esters; silicones;cellulosic polymers, e.g. KY-Jelly (available in the UK from Johnson &Johnson). Mixtures of any of the aforesaid are also intended to becovered.

[0044] The frangible member may comprise at least one line of tear,break, fracture or breach, or other points, or at least one other lineor region of brittleness, fragility or weakness. Such a member is thuscapable of collapsing and/or tearing, breaking, bursting, cracking orsnapping or tearing or breaking down under stress.

[0045] In a further embodiment it may be desirable that one or moreportions of the first chamber and/or the second are movable relative tothe rest of the packaging system.

[0046] In use, a tampon housed in the first chamber is pushed into thesecond chamber, breaking the frangible member. The substratesubstantially coats the nose and shoulder of the tampon. The twochambers may then be opened to facilitate removal of the substantiallycoated tampon.

[0047] The method of opening may vary depending upon, inter-alia, themethod of construction employed for the chambers. However, ashereinbefore described, in a preferred embodiment, the chambers areformed by crimping the edges of the two walls of the chamber such thatone wall may simply be peeled away from the other. The chambers, andespecially the first chamber, may be provided with means to facilitatepeeling of the wall. Such facilitation means may comprise a liftable tabat a comer of the chamber or at one end of the chamber. Alternatively,at least a portion of the periphery of the chamber may be perforated orcut away, e.g. notched to allow an end of the chamber to be torn.Preferentially the facilitation means is provided adjacent the end ofthe chamber distal to the frangible member.

[0048] In order to move the sanitary product into contact with thesubstrate, or vice versa. The term“movable” includes, forexample,“compressible” and“squeezable” relative to the rest of theapplicator and/or packaging system.

[0049] In another embodiment of the invention, the system may comprise atampon applicator. Thus, according to a further feature of the inventionwe provide a sanitary article packaging system which comprises a firstchamber for housing a sanitary article applicator and a second chamber,adapted to act as a substrate reservoir, the first and second chambersbeing separated by a frangible member. Means may be provided such as apiston or plunger slidable within the housing means to drive the tamponout of the applicator.

[0050] Thus in a preferred embodiment of the invention the systemcomprises a cylindrical housing such that the membrane is radial to thecylinder. The substrate reservoir preferentially lies at one end of thecylinder.

[0051] In the applicator of the invention the second reservoir chambermay be provided with an openable end wall. Alternatively it may simplycomprise an open wall with a removable cover. The cover may be acardboard or plastics cover or may be, a plastics film, e.g. cellophane.The openable end wall is preferentially the wall distal to the membrane.

[0052] Thus it will be intended that the tampon be fluid-lubricated forapplication on its removal from the applicator across all or a majorproportion of its absorbent surfaces by passage of the entire tamponproduct through the fluid lubricant.

[0053] It may be desirable that the first and second chambers are in theform of two coaxial hollow cylindrical chambers, containers or otherreceptacles of the same diameter but unequal axial length with afrangible or collapsible intervening wall or barrier, as hereinbeforedescribed.

[0054] Thus, the absorbent sanitary product (a bullet-shaped catamenialtampon) may be housed in the larger chamber, container or otherreceptacle, which is the housing, with its nose towards and/or againstthe frangible wall or barrier, and a fluid lubricant may be held in thesmaller chamber, container or other receptacle, which is thus thereservoir.

[0055] Alternatively, the first and second chambers may possessdifferent diameters so that one may be slidable within the other.

[0056] The reservoir may optionally decrease in internal diametertowards end distal to the membrane. For example it may taper down and/orbe domed or have at least one step change in internal diameter.

[0057] In one form, the side walls of the lubricant reservoir may extendbeyond the closure membrane, film or sheet in the form of a domecovering the closure membrane. Additionally or alternatively, themembrane may be integral with the side walls and may optionally bedomed.

[0058] For an applicator tampon it may be undesirable for the tamponapplicator to be driven through the frangible membrane and through thefluid lubricant in the reservoir as there is a high risk that the tamponmay be expelled from the applicator. Thus, although in one embodiment anapplicator tampon may be used to break the frangible membrane, it ispreferred that the reservoir chamber is squeezed causing the material,eg a lubricant to rupture the frangible member and to be squeezed ontothe nose of the applicator. Thus when the tampon is administered via theapplicator, the nose of the tampon is coated as it is ejected from theapplicator; in addition to the lubrication of the applicator itself.

[0059] According to a further feature of the invention we provide atampon applicator as hereinbefore described wherein said applicator alsohouses a tampon and a substrate.

[0060] When the applicator reservoir houses a medicament, such as anantifungal agent, the tampon and/or the applicator may be used in thetreatment of certain disorders and may be used as an alternative to apessary.

[0061] Thus according to the invention we further provide a method ofintravaginal delivery of a medicament which comprises the use of asanitary article packaging system as hereinbefore described.

[0062] We further provide a method of treating a vaginal disorder whichcomprises delivering a medicament, drug, cosmetic, hormone or aprobiotic using a sanitary article packaging system as hereinbeforedescribed.

[0063] Examples of such disorders include bacterial, microbial, fungaland parasitic infections or related medical disorders or any combinationof the foregoing.

[0064] According to yet a further feature of the invention we providethe use of a cellulosic based lubricant and/or KY-Jelly in themanufacture of a prefilled sanitary article packaging system ashereinbefore described.

[0065] In a further feature of the invention the packaging system may beprovided with a fastening means for releasably securing the packaging ina folding arrangement. This feature is especially advantageous when thesystem is used with a sanitary article, although it will be understoodthat the use of fastening means should not be limited to use withsanitary articles.

[0066] The fold may be a C or an S fold or any conventionally used fold.However, preferentially, the fold is a C fold and particularly a foldalong the line of the frangible member. When the frangible membercomprises the crimped walls of the chambers then a natural fold line isproduced.

[0067] The fastening means may be any conventionally known fasteningused in connection with, for example, sanitary articles. Thus, thefastening means may comprise an area of adhesive applied to a surface ofthe outer wall of one or both of the chambers. Preferably, the fasteningmeans comprises an adhesive tab such as is described in U.S. Pat. No.5,484,636, which is incorporated herein by reference.

[0068] Thus, the adhesive tab comprises a first end which is coated, onone side, with a relatively strong adhesive. The first end of theadhesive tab being fixed to an end of either the first or secondchambers. Preferably the first end of the tab is fixed to the end of thesmaller of the two chambers, usually the second chamber, i.e. thesubstrate reservoir. The end of the chamber to which the adhesive tab isfixed is usually the end distal to the frangible member.

[0069] A second end of the adhesive tab is coated, on one side, with arelatively weak or at least peelable adhesive. Alternatively, anadhesive may be provided with a ‘dead’ adhesive area for ease ofopening.

[0070] The use of such a tab has the benefit that the packaging systemsmay present in a folded form which, particularly in the case of sanitarytampons, allows them to be carried discreetly. Moreover, once thepackaging has been used it may be folded or rolled and the adhesive tabused to fasten the packaging together to aid disposal. Alternatively,the used packaging may itself be used as a receptacle for used or soiledsanitary articles, e.g. a tampon. Thus the used tampon may be placed inthe first chamber and the packaging system folded or rolled as hereinbefore described for disposal.

[0087] Referring to FIG. 1, a packaging system (11) comprises alongitudinal cylinder and is provided with a first chamber (12) and asecond chamber (13). The chambers (12 and 13) being separated by afrangible member (14). The first chamber (12) is adapted to house anarticle (15), e.g. a tampon. When the article is a tampon whichcomprises a domed end (16) and a flat distal end (17) and the secondchamber (13) houses a substrate (18), e.g. a lubricant.

[0088] Referring to FIG. 2, in use, the tampon (25) is pushed via itsflat end (26), either by hand or using a plunger, so that the domed end(26) breaks the frangible member (24). The tampon (25) then enters thereservoir of the second chamber (23) and contacts the substrate (28).

[0089] Referring to FIG. 3, the tampon (35) is removed from the secondchamber (33), by retracting it through the frangible membrane (34), thetampon (35) being coated with substrate (38).

[0090] FIGS. 3 to 6 provide a longitudinal cross-section view of theprocess illustrated in FIGS. 1 to 3.

[0091] Referring to FIG. 7, the end (711) of the first chamber (72),distal to the frangible member (not shown) is provided with anon-crimped, releasable region (710), which facilitates peeling apartthe walls (711 and 712).

[0092] Referring to FIG. 8, the end (811) of the first wall (89) ispeeled away from the end (812) of the second wall (89).

[0093] Referring to FIG. 7, the end (79) of the first chamber (72),distal to the frangible member (74) is provided with a non-crimpedportion (10) which facilitates peeling apart of the walls (711 and 712)of the first chamber (72) and, optionally, the second chamber (73).

[0094] Referring to FIGS. 9 to 11, a packaging system (91) of theinvention is used to house an applicator tampon (93). Thus, in use thesecond chamber (93) is squeezed causing the frangible member (94) torupture, the lubricant (98) coats the applicator tampon (93).

[0095] Referring to FIG. 12, the packaging system (121) is folded aboutthe crimp line (124) between the first and second chambers (122 and123). The end (125) of the second chamber (123) distal to the crimp line(124) is provided with a tab (126). A first end (127) of the tab (126)is coated with a relatively strong adhesive and is attached to the end(125) of the second chamber (123). A second end (128) of the tab (126)is coated with a relatively weak, peelable, adhesive. The second end(128) is attached to an outer wall of the first chamber (122). In use,the second end of the tab (126) may be peeled away to allow thepackaging system to be used. After use, the packaging system may berolled up and held together by re-adhering the second end (128) of thetab (126). Alternatively the used system may be used to discreetlydispose of soiled articles.

[0096] Referring to FIGS. 13 to 15, a packaging system (1) of theinvention is used to house e.g. a yoghurt (1313) and a fruit sauce.

[0097] Thus, in use either the first (141) or the second chamber (143)is squeezed causing the frangible member (144) to rupture. The yoghurt(1513) and fruit sauce (153) are mixed around the point indicated as(155).
